Answer 1

是JDK版本问题= = 改成1.8的JDK就好了

    public static void main(String[] args) throws Exception {

        XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()

        AbstractXMPPConnection conn1 =new XMPPTCPConnection(config);
        conn1.connect();
        conn1.login();
        System.out.println(conn1.getHost());
        System.out.println(conn1.isConnected());
        System.out.println(conn1.getUser());


        Chat chat = ChatManager.getInstanceFor(conn1).createChat("xiaoming@sun-d601bacdc00");

        chat.addMessageListener(new ChatMessageListener() {
            public void processMessage(Chat chat, Message message) {
                System.out.println(message);
            }
        });
        while (true) {
            chat.sendMessage("lalalal");
            Thread.sleep(5000);
        }
    }
}

以上代码在我这是可以发送消息的
